Sorry guys, I didn't realize the wiring could be different on first gens. I forgot about the whole 05 refresh deal. My vibe is a 2003 GT. And THANK YOU to all those who posted up wiring diagrams!!
I'm doing the stereo install this weekend and it will help so much! I've already run 3 RCA cables, 4 speaker wires, amplifier remote wire, amplifier volume knob wire from the rear to the front on the passenger side and the 4 gauge power cable on the driver side so I'm all ready to go when the head unit arrives weds in the mail.
Side note, any advice on wiring the door speakers from a trunk mounted 5 channel amp? Right now I plan on using the speaker wires I ran from the amp up to the dash to connect to the car wiring harness where it would normally hook up to the head unit...
